Frequently asked questions
Jump to a question:
Can I repot my Cactus?
Absolutely! It is recommended to increase the size of the container as the plant becomes larger over time, however the new planter should not be oversized as a tighter fit gives the cactus and roots more stability in loose and well draining soil. An proper example would be to go from a 4" pot to a 6" pot.
What kind of soil should I use?
Use a well draining soil. The roots of the San Pedro cactus dislike being submerged in water. If they get too wet and too cold they begin to rot leading to "root-rot". This can be avoided by watering well draining soil more frequently in warmer weather rather than keeping it soaked in heavier dirt. We recommend and use Bonsai Jack #111 Succulent and Cactus soil.
Should I use fertilizer?
Plants need more than just tap water. For aggressive vegetative growth we recommend a water mixture of General Hydroponics Flora Series with Cal-Mag by Botanicare. Follow the instructions on the labels accordingly and your cactus will have the nutrients it needs for healthy growth. Optimal pH is between 6.2-7.2 and for that General Hydroponics offers ph Down. All of these products can be easily found doing a search on common sites like Amazon.com, Walmart.com, Google.com and more.
What do I do in winter?
You can continue to encourage active growth if you have sufficient lighting and continue to water it. If you do not live in a Cacti friendly plant zone this can be circumvented by positioning your cactus in an area where it can receive several hours of sunlight each day. Ideally, place it near a south or southeast-facing window that allows for ample natural light. The cactus should not be left outside in temperatures lower than 50F, although it can survive some lower temperature shocks.
Why is my cactus getting skinny?
If the tip of the Cactus is getting smaller and skinnier as it grows taller it is a sign of etiolation. Essentially more light is needed to encourage better growth. This may happen over the winter months and is nothing to worry about if caught early.
Is a San Pedro Cactus Toxic?
Yes, it is very poisonous! Be extremely careful if the Cactus is around Children or Pets. Immediately consult a doctor if ingested.
What are these spots and bumps?
As time passes you may begin to notice areas that may have a different color or shape. Some spots may be raised like bumps. Sometimes these can be concerning and need our help, and sometimes they can be overcome naturally by the cactus. Spots may be a sign of stress, like being hit by an object, falling over, or being abused by a curious insect or animal. Sometimes they have been scratched or poked by a neighbor, and sometimes it may be from too much sun or water.. or a lack thereof. Many "spots" are cosmetic and nothing to worry about, just keep an eye on them and note the progress in your journal. Sometimes these bumps may even be new cacti or new roots!
